To all whom it may concern:

`Be it known that I, JOSEPH S. DUNCAN, a `citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois', have invented new and useful Iniprovements in Printing-Plateaof which the following Ais a specification. l

rlhe object of this invention is to provide a printing plate of inexpensive construction which is adapted to be Stored in standing position on one end in a tray or drawer and properly indexed according to a card in dex system and spaced so that the printing characters of each plate will be protected from engagement with adjacent plates.

In the accompanying drawings Figure 1 shows a portion of an index plate embodying iny invention with the index tab in one position thereof. Fie. 2 shows an entire index plate with the index tab at another position.

. Fig. 3 is an end view-of the plate shown in "Fig 2.- Fig. 4; shows an entire index plate with the index tab in another position and the type in relief on the saine side of the plate with the spacing' flanges. Fig. 5 is an end View of the plate shown in Fig. il. p

The plates are preferably made of metal which will permitthe printing characters to be stamped in relief thereon but the printing characters may beotherwise applied, if de' sired. These plates are also preferably inade oblong in shape with the lines of type there on running lengthwise of the plate. rll`he short edges constitute the top and 'bottom ofthe late. The Ilong edges of the 'plate 7 are bent over to forni spacing flanges Sso that a number of plates may be nested onel against the other without contacting with the faces of the printing'characters 9. These spacing 'tlangeshinay be arranged at the back of the plate, as shown in Figs. 1,2, and 3, or at the front of the plate, shown in Figs. fl and 5. y

'Each index plate isprovided at its top' with an index tab made integral therewith and projecting above the plate suficiently to he easily read in the tray Aor drawer in ie located in staggered relation to facilitate l the reading thereof. Thus, in Fig. 1 the tab' f' l() is located at the left of the top of the plate; in Fig. 2 thetab 1l is loca-ted at the center of the top of the plate; in Fig. 4e the, tab is located at the right side of the top' of the plate. These indextabs may be made of any suitable size to receive one or more index characters as desired and these characters may be stamped, printed or otherwise applied to the tab in any suitable manner.v

lt is contemplated using the index plates with a plurality'of plain plates without the tabs so that in the tray or drawer the tabs of the indexv plates will project aboiethe top of the plates to be clearly displayed and l easily read.

1What- I claim and desire to secure by Letters Patent is t in oblong printing plate having printing .characters on one side in lines running lengthwise thereof, and raised above. 4the surface of the plate, the long edges of said plate constituting the sides, and the short edges constitutingl the top and bottoni thereof, said plate being made out of a single sheetof metal and having its long edges bent inwardly to 'form spacing flanges on one side of the plate to prevent contact of the plates with the printing characters ,when a number of plates are arranged in4 a stack, and an index tab integral with the plate and projecting upwardly from the short. top edge thereof, and above the long side edges of the plate, whereby the plates are adaptevd to be placed in a deep, narrow receptacle so that their index tabs will be separated from each other by the spacing flanges and readily WM. 0.
